I also have a Tiger II  with a Magnum 46 on it. It flys just fine with it. I have had a TT Pro 46 a 55 AX and a Tower Hobbies 46 on it. Ofcourse the 55 made the most power but I really can't tell any difference in the other three. I will say I believe for the money the TT Pro is the best deal out there for the money.
